# Evasion Attacks ⎊ Area ⎊ Greeks.live --- ## What is the Threat of Evasion Attacks? Evasion attacks represent a significant threat to machine learning models employed in financial decision-making, aiming to manipulate inputs to bypass security mechanisms or trigger incorrect predictions. These attacks involve crafting adversarial examples that appear benign to human observers but cause models to misclassify or misinterpret data. In the context of derivatives, an attacker might modify trading signals or market data to avoid detection by fraud systems or risk management algorithms. Such threats compromise automated trading integrity. ## What is the Technique of Evasion Attacks? Attackers typically employ gradient-based optimization methods to generate evasion examples, subtly perturbing input features to cross a model's decision boundary. Common techniques include Fast Gradient Sign Method (FGSM) or Projected Gradient Descent (PGD), which iteratively refine inputs to maximize misclassification probability. These methods exploit the inherent sensitivity of deep learning models to small, targeted perturbations. The goal is to induce a desired, erroneous output. ## What is the Detection of Evasion Attacks? Detecting evasion attacks requires implementing robust anomaly detection systems that monitor input data for subtle, non-random perturbations. Statistical analysis of input distributions and comparison with expected feature ranges can help identify suspicious patterns. Employing adversarial training, where models are trained on both clean and adversarial examples, enhances their resilience to such manipulations. Continuous model retraining and monitoring of model output deviations are critical for maintaining security. --- ## [Bridge Governance Attacks](https://term.greeks.live/definition/bridge-governance-attacks/) Manipulation of decentralized voting processes to authorize malicious changes to a bridge protocol. ⎊ Definition ##
